New YORK, A CORPORATION or NEW YORK Application filed November 18, 1907.Serial No.l 402,627.

To all 'u-l om it may concern.'

. Be it known that I, LUKE F. GILLEsrlE, a citizen of the United States,residing at Newburgh,V in the county of Orange and Statewof New York,have invented an Im- )rove-ment in Picker-Stick Connections for ooms, ofwhich the following is a speciication.

My invention relates to an improvement in picker-stick connections forlooms. Heretofore the lug strap connecting the picker stick to thesweep-stick has ordinarily been made of leather, the relation of whichwas maintained to the ic-ker-stick by a loop of leather secured to rolesmade in said stick. The adjustn'ient of the lug strap was effected byother holesin the picker-stick and these holes weakened the picker-stickand the lug strap would stretch and wear.

The object of my invention is to increase 'the useful life of thepicker-stick and to lend prominence to the other parts by the employmentof a. lug strap of substantial character and means for adjustably Turingthe position of the same upon the picker-stick without the necessity ofperforating the said stick.

Incarrying out my invention, I provide a lug strap of metal of elongatedU-form to straddle the picker-stick, a bunter Of leather or similarmaterial in the bend of the strap securely held in place, and eyes inthe other or free ends of the lug strap for a bolt for connecting thestrap to the sweep-stick of the-loom.

The picker-stick is of usual character (wit-hout weakening holes)pivotally connected to a base of the loom and at its upper end providedwith a icker to hit the shuttle and throw it across t 1e loom.

I provide means preferably in the form of adjusting clips secured to thepicker stick both above and below the lug strap for positioningthe lugstrap as desired and adjusting the same to regu ate the extent ofmovement or travel imparted to the said stick and so to control theforce of the blow upon the shuttle. These cips are preferably made withcurved parts for the eyes of the lugstrap to bear against.

In the drawing, Figure 1 is a side elevation and Fig. 2 an edgeelevation representing the devices of my improvement and Fig. 3 is asectional plan at the dotted line sc, I, of Fig. 1.

PICKER-STICK CONNECTION FOR LOO MS.

Patented Aug. 4, 1908.

The picker stick b is connected by a pivot shaft 2 to a cast base ay ofthe loom. vThe picker stick is preferably of wood and of usualcharacter, and at the upper free end thereof a picker c also of usualcharacter is secured to the stick against which the shuttle strikes atthe end of its movement and by which with the further movement of the-stick b and in the bend thereof there is a buntcrof leather or oth'ersuitable material connected in place by a bolt 4 which asses through thelug-stra and througi the bunter; the surface oi) the bunter bearing`against an edge of the pickerstick.

I provide means for positioning the lugst-rap and determining therelation thereof along the picker-stick and its distance from thc pivotshaft 2, and this means is preferably in the form of adjusting clips.These clips are made alike but reversed 1n position. Each clip comprisesa yoke 7L of metal with free threaded ends on which there are nuts h*and a plate 'i notched and provided with forked or curved ends i. .Theplate i presses against the back edge of the pickerstick while the. bentportion of the yoke passes around the frontv edge of the ickerstick andthe threaded ends of the yo te. pass 9 through holes in the plate andthe nuts clamp the parts togetherupon the picker-stick. The curved endspass ove;` tie opposite faces of the picker-stick toward the cent-er andwhen these clips are arranged in oppo- 100 site ositions the said curvedends il come closey adjacent to the opposite top and bottom edges of thelug-strap Il; in fact the lug-strap d rests upon the. curved ends of thelower clip rocking thereon with the 105 swinging movement of thepicker-stick and should the. yoke strap as tie result of the momentum ofthe parts tend to rise from its Support on the lower clip it willmomentarily come in contact with the curved ends of the 11eA upper clip,its upper movement being arrested and it temporarily rocking on the ycurved ends of the upper clip.

The greater the movement to be given to the picker-stick the nearer willthe lug-strap be brought to the pivot shaft 2 because the -sweepstick ehas a recognized .amount of movement and the smailer the extent ofmovement to be given the picker-stick t-he further away from the pivotshaft 2 is the. lug-strap placed. ln this way the extent of. movementdesired is easily adjusted or regulated.

The )arts are strong, substantial, readily secure( and adjusted. Theiruse does not make it necessary to weaken the pickerstick by making holestherein, consequently the initial strength of the picker-stick ismaintained and the parts being of `substantial character their usefullife is very considerable.. i

I claim as my invention:

, 1. The combination with apicker-stick and a sweep-stick, of a metallug-strap adapted to straddle the picker-stick, a'bolt connecting thelug-strap to the svreep-stick, a bunter and bolt for securing the samebetween parts of theA lug-strap and separate and independent adjustablemeans secured to the pic-ker", stick both above and below thelug-st-rap'for adj ustably locating t-he lug-strap and guiding the same.

2. The combination with a picker-stick and a sweep-stick, of a metallug-strap adapted to straddle the picker-stick, a bolt connecting thelug-strap to the sweep-stick, a bunter and bolt for securing the samebetween parts of the lug-strap and spaced apart, separate andindependent means secured to the picker-stick beth above and below thelug-strap for locating the lug-strap and guiding the same.

3. The combination with a metal base and a tapering wooden picker-stickand wooden sweep-stick, of a metal lugsirap of elongated U-form adaptedto stradeile the picker-stick, a bolt connecting the lug-strap at itsfree ends to one end of the sweep-stick, a bunter of leather or similarmaterial Within the bent portion of the lug-strap with the surfacevlug-strap and spaced apart, separate and independent means secured tothe picker-stick both above and .below the lug-strap 'for loeating thelug-strap along tl1e"'picker-stick yand guiding the same.

4. The combination with a metal base and a tapering wooden sweep-stick,of a metal lug-strap of elongated U-form adapted to straddle thepicker-stick, a bolt connecting the lug-strap at its free ends to oneend of the sweep-stick, a bunter of leather or similar material withinthe bent portion of the lug-strap with the surface thereof 'comingagainst the edge of the picker-stick, abolt for securing the bunter tothe lug-strap and means each comprising a. yoke straddling thepicker-stick, a plate with holes engaged by the yoke and nuts forsecuring the parts together and curved ends to the said plateabove andbelow the lug-stra p for adjustably locating the lug-strap and guidingthe same.

5. The combination with a metal base and a wooden sweep-stick, of ametal lug stra adapted tostraddle the picker-stick, a bo t connectingthe lug strap to one. end of. the swee -stick, a bunter of leather orsimilar materia secured within the lug strap, with a'. surface thereofcoming against the edge of the picker-stick and means each comprising aYoke straddling the picker-stiek, a plate with holes engaged by theyoke, and nuts for securing the parts together, and curved ends to thesaid plate coming at either side of t-he picker-stick both above andbelow the lug strap for adjustably locating the lug strap and guidingthe same.
